非交错网格下Boussinesq方程的源函数产生波浪的方法
Methods for generating waves using a source function in Boussinesq equation wish Non-staggered Grids
【摘要】 针对由Beji型的Boussinesq方程推导出的在计算域内产生波浪的源函数,应用有限差分法的Adams-Bashforth-Moulton预报校正格式,在非交错网格下进行数值模拟。在一维方向上进行离散,对一维平底地形和潜堤地形进行了数值模拟,数值计算结果与物理模型试验结果吻合较好,表明采用源函数的方法可以很好地在数值计算域内产生波浪。
【Abstract】 Based on the source function that generates waves in the computational domain deduced by Beji Boussinesq equation,a composite 4th-order Adams-Bashforth-Moulton scheme is used to simulate wish non-staggered grids.Dispersed in one dimension,it simulates constant water depth and submerged dyke topography.Compared numerical result and the experimental data,numerical data that use the source function agree well with the experimental data and numerical data that use generating boundaries.It suggests that this method using source function to generate waves in computational domain could simulate wave propagate well.
